Brucellosis is a zoonotic and economically significant animal disease worldwide. The most frequently used vaccine to avoid brucellosis in small ruminants the Rev1 conjunctival Brucella melitensis vaccine. aim of this study was investigate effects B.melitensis Revl on total protein, albumin, globulin levels, protein profiles oxidant/antioxidant status sheep. Ten sheep were as material for purpos...
When a pathogen infects a number of different hosts, the process of determining the relative importance of each host species to the persistence of the pathogen is often complex. Removal of a host species is a potential but rarely possible way of discovering the importance of that species to the dynamics of the disease. This study presents the results of a 12-year programme aimed at controlling ...
Aborted sheep foetuses were collected during the lambing seasons of 2004 to 2006. B. melitensis was isolated from 25 (29.76%) of 84 lungs and stomach contents. Based on the biochemical tests and agglutination test with monospecific A and M antisera, the isolates were determined as B. melitensis biotype 3. The isolation of the B. melitensis from aborted sheep foetuses may show the importance of ...
The true prevalence of brucellosis and diagnostic test characteristics of three conditionally dependent serological tests were estimated using the Bayesian approach in goats and sheep populations of Bangladesh. Serum samples from a random selection of 636 goats and 1044 sheep were tested in parallel by indirect ELISA (iELISA), Rose Bengal Test (RBT) and Slow Agglutination Test (SAT). The true p...
The authors present the epidemiological status of brucellosis in cattle and small ruminants in Syria from 1990 to 1996, based on laboratory findings at the Brucellosis Centre, Damascus. Initial investigations using the Rose Bengal plate test, the complement fixation test and a miniaturised variant of the slow agglutination test were conducted throughout the country in 1990 and 1991, revealing a...
The prevalence of brucellosis was determined in the ruminants (buffaloes, cattle, sheep and goats) of five different districts viz. Bagerhat, Bogra, Gaibangha, Mymensingh and Sirajgonj of Bangladesh. A total of 550 sera samples of 105 buffaloes, 188 cattle, 127 goats and 130 sheep were screened by RBT and were further confirmed with I-ELISA. A structured questionnaire was used to collect epidem...
Group 3 of outer membrane proteins (OMPs) of Brucella includes Omp25 and Omp31, which share 34% identity. Omp25 is highly conserved in Brucella species, and Omp31 is present in all Brucella species, except Brucella abortus. Antibodies to Brucella melitensis Omp31 have been sought only in infected sheep, and Western blotting of sera from infected sheep did not reveal anti-Omp31 reactivity. We ob...
Brucellosis has been an endemic disease of cattle and humans in Costa Rica since the beginning of XX century. However, brucellosis in sheep, goats, pigs, water buffaloes, horses and cetaceans, has not been reported in the country. We have performed a brucellosis survey in these host mammal species, from 1999-2016. In addition, we have documented the number of human brucellosis reported cases, f...
Background and Objectives: Brucellosis is one of the most important zoonosis diseases. The aim was to estimate the seroprevalence of brucellosis in rural cattle, sheep, and goat of Bushehr Province. Methods: This cross-sectional study was conducted in 2012-2014. For the cattle population, a total of 118 villages and 891 cattle and for sheep and goat population, a total of 202 villages, 526 flo...
Brucellosis being a global zoonotic disease and animal health problem most of the studies has been oriented towards bovine than small ruminants. Hence the present study is conducted to identify the biotype of predominant Brucella spp. in small ruminants for defined control and eradication strategies. The study was carried out by random collection of the vaginal swab, milk, blood samples from th...
